CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to pending U.S. Provisional Application Ser. No. 61/594,992, entitled “DOCUMENT ASSEMBLY AND AUTOMATED CONTEXTUAL FORM GENERATION”, filed on Feb. 3, 2012, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

This disclosure is generally related to a user interface for assembling documents and generating automated contextual forms.

BACKGROUND

Digital media can be imported from external devices (e.g., cameras) onto personal computers for storage. Users can view the imported digital media on the personal computer once the digital media has been imported.

SUMMARY

This disclosure describes various Graphical User Interfaces (GUIs) for implementing various features, processes or workflows. These GUIs can be presented on a variety of electronic devices including but not limited to laptop computers, desktop computers, computer terminals, television systems, tablet computers, e-book readers and smart phones. One or more of these electronic devices can include a touch-sensitive surface. The touch-sensitive surface can process multiple simultaneous points of input, including processing data related to the pressure, degree or position of each point of input. Such processing can facilitate gestures with multiple fingers, including pinching and swiping.

When the disclosure refers “to select” or “selecting” user interface elements in a GUI, these terms are understood to include clicking or “hovering” with a mouse or other input device over a user interface element, or touching, tapping or gesturing with one or more fingers or stylus on a user interface element. User interface elements can be virtual buttons, menus, selectors, switches, sliders, scrubbers, knobs, thumbnails, links, icons, radial buttons, checkboxes and any other mechanism for receiving input from, or providing feedback to a user.

This disclosure describes systems, methods, and computer program products for assembling documents on a computing device. A first document, e.g., a document in a portable document format, can be presented in a graphical user interface (GUI). Thumbnail images of one or more pages in the first document can also be presented on the GUI. A user can select an option for inserting one or more pages from a second document into the first document. The user can also indicate a position in the first document where the one or more pages of the second document will be inserted. The one or more pages of the second document can be in a file format, e.g., a portable document format, in an un-digitized format, or can be a blank page. Document pages in an un-digitized format can be digitized using a document scanning device using document settings derived from the first document, and can be inserted into the first document. In some implementations, a scan resolution, a scan area size, a color depth, and a desired post-processing can be derived from a document. The modified first document can be presented on the GUI, where the user can continue inserting pages from the second document into the first document.

In some implementations, a method comprises: displaying one or more pages of a first document in a first region on a user interface; displaying thumbnail images of the one or more pages of the first document in a second region on the user interface; receiving user selection for inserting one or more pages from a non-digitized second document into the first document; and in response to the user selection, digitizing the one or more pages of the non-digitized second document using a document scanning device, and inserting the one or more pages of the digitized second document into the first document, wherein the inserted pages are displayed as part of the first document on the user interface.

In some implementations, a system comprises one or more processors and memory coupled to the one or more processors. The memory is configured for storing instructions, which, when executed by the one or more processors, causes the one or more processors to perform operations. The operations comprise displaying one or more pages of a first document in a first region on a user interface; displaying thumbnail images of the one or more pages of the first document in a second region on the user interface; receiving user selection for inserting one or more pages from a non-digitized second document into the first document; and in response to the user selection, digitizing the one or more pages of the non-digitized second document using a document scanning device, and inserting the one or more pages of the digitized second document into the first document, wherein the inserted pages are displayed as part of the first document on the user interface.

Other implementations are disclosed that are directed to methods, systems and computer-readable mediums.

This disclosure also describes systems, methods, and computer program products for automated contextual form generation on a computing device. A first document, e.g., a document in a portable document format that includes one or more non-digitized form fields can be presented in a GUI. A user can select a position in the first document. In response to the selection, a non-digitized field located in proximity to the selected position can be identified. If a non-digitized field is identified, the non-digitized field is digitized, where digitization of the non-digitized field allows the ability to electronically edit the non-digitized field.

In some implementations, a method comprises: displaying a first document on a user interface, the first document containing one or more non-digitized fields; receiving a user selection of a position in the first document; in response to the user selection, identifying a non-digitized field located in proximity to the selected position; and if a non-digitized field is identified as being located in proximity to the selected position, digitizing the non-digitized field.

In some implementations, a system comprises one or more processors and memory coupled to the one or more processors. The memory is configured for storing instructions, which, when executed by the one or more processors, causes the one or more processors to perform operations. The operations comprise displaying a first document on a user interface, the first document containing one or more non-digitized fields; receiving a user selection of a position in the first document; in response to the user selection, identifying a non-digitized field located in proximity to the selected position; and if a non-digitized field is identified as being located in proximity to the selected position, digitizing the non-digitized field.

Other implementations are disclosed that are directed to methods, systems and computer-readable mediums.

Particular implementations of the document assembly and automated contextual form generation application disclosed herein provide one or more of the following advantages. Users can insert non-digitized documents directly into a document being viewed in a GUI. Users can indicate, using the GUI, a position in the document where pages from the non-digitized document should be inserted. Non-digitized form fields and check boxes in an electronic document can be digitized based on user selections of the non-digitized form fields and check boxes.

The details of the disclosed implementations are set forth in the accompanying drawings and the description below. Other features, objects, and advantages will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION

The disclosure that follows describes a document assembly and automated contextual form generation application. A user can select an option for inserting one or more pages from a second document into the first document. The user can also indicate a position in the first document where the one or more pages of the second document will be inserted. The one or more pages of the second document can be in a file format, e.g., in an image or a portable document format, in an un-digitized format, or can be a blank page. The blank page need not exist in a particular file format or an un-digitized format and can be generated by the computing device. Document pages in an un-digitized format can be digitized using a document scanning device, where the document pages are formatted using document settings derived from the first document, and can be inserted into the first document. The modified first document can be presented on the GUI and the user can continue inserting pages from the second document into the first document.

The application can also automatically generate contextual forms in a first document, e.g., a document in a portable document format that includes one or more non-digitized form fields. A user can select a position in the first document. In response to the selection, a non-digitized field located in proximity to the selected position can be identified. If a non-digitized field is identified, the non-digitized field is digitized, where digitization of the non-digitized field allows the ability to electronically edit the non-digitized field.

Exemplary GUI for Document Assembly

FIG. 1 illustrates an exemplary GUI 100 depicting a first document 106. The GUI 100 includes a first region 102 for displaying one or more pages of the first document 106 and a second region 104 for displaying thumbnail images of the one or more pages of the first document 106. The first document being displayed on the GUI 100 can be a file that is stored on a computing device on which the GUI 100 is executing.

In FIG. 1, a page of the first document 106 is displayed in the first region 102 of the GUI 100. In addition, thumbnail images 108 and 110 that correspond to pages in the first document 106 are displayed in the second region 104. A user can select one of the thumbnail images 108 and 110 to display a page corresponding to the thumbnail image in the first region 106. In particular, thumbnail image 108 is shown with a border 112 indicating that the page corresponding to the thumbnail image 108 is currently being displayed in the first region 106.

The computing device can be, for example, a personal computer, laptop, tablet, a handheld computer, a personal digital assistant, a cellular telephone, a smart phone, a media player, an email device, a game console, or other electronic device, or a combination of any two or more of these data processing devices or other data processing devices. The first document can be stored, for example, on other computing devices, external devices (e.g., cameras, portable hard drives, flash drives, network-attached storage devices), or cloud-based storage systems.

The accompanying drawings show a mouse cursor but other pointers, including human fingers, can be used with devices having touch sensitive surfaces.

FIG. 2 illustrates an exemplary GUI 200 depicting a first document 206 and options 212 for inserting a second document. The GUI 200 includes a first region 202 for displaying one or more pages of the first document 206 and a second region 204 for displaying thumbnail images of the one or more pages of the first document 206. The GUI 200 also includes options 212 for inserting a second document into the first document. The second document can be a file that is stored on a computing device on which the GUI 200 is executing. Further, the second document can be stored, for example, on other computing devices, external devices (e.g., cameras, portable hard drives, flash drives, network-attached storage devices), or cloud-based storage systems.

In FIG. 2, a page of the first document 206 is displayed in the first region 202 of the GUI 200. In addition, thumbnail images 208 and 210 that correspond to pages in the first document 206 are displayed in the second region 204. The options 212 can be used to insert one or more pages of a second document into the first document. An option 214 can be selected to insert pages from a non-digitized second document, e.g., a document that is available as a hard copy, into the first document using a document scanning device, e.g., a scanner. A user can also select an option 216 to insert pages from a second document that is stored as a file. Additionally, an option 218 can be selected to insert one or more blank pages into the first document 206.

In some implementations, the option 214 can be selected to insert pages from a non-digitized document and, in response to the selection, a new document is created in which the pages from the non-digitized document will be added. Document settings for the new document, e.g., page formatting and size, can be determined based on the pages of the non-digitized document, e.g., the first inserted page, as they are scanned by a document scanning device.

In some implementations, a document scanning device used to insert pages from a non-digitized second document includes a document feeder. In some implementations, multiple pages of a non-digitized second document can automatically be inserted from a document scanning device. In some implementations, after each page is scanned, the scanned page is inserted into the first document and the page insertion position is incremented into a subsequent position.

FIG. 3 illustrates an exemplary GUI 300 depicting digitization of a second document 306. The GUI 300 includes a first region 302 for displaying digitized pages of the second document 306 and a second region 304 for displaying thumbnail images 308 and 312 of the pages of a first document and inserted digitized pages of the second document 306.

In FIG. 3, a page from the second document 306 is depicted as being digitized using a document scanning device. The document scanning device can be a device that optically scans items in physical form, e.g., printed images, printed text, printed handwriting, or objects, and converts the items to a digital image. The GUI 300 can display portions of the page being digitized during the digitization process. The GUI 300 can display a message 314 indicating that digitization of a page from the second document 306 is in progress.

The second region 304 also depicts a placeholder 310 indicating a position in the first document in which the digitized page of the second document 306 will be inserted. In some implementations, the placeholder 310 can be specified by the user. The user can drag-and-drop the placeholder 310 in the second region 304 to specify an insertion position among the thumbnail images 308 and 312 corresponding to pages in the first document. The user can cancel the digitization process by selecting a cancel button 316. The cancel button 316 can cancel the currently ongoing scanning process. A user can select the cancel button 316, for example, to abort a scanning process to adjust the position of the second document in the document scanning device. The button 318 can be selected to exit the inline scan mode in the GUI 300. The GUI 300 can remain in scan mode until the button 318 is selected, thereby allowing a user to continue inserting pages into the first document. Once the button 318 is selected, the GUI 300 switches to a normal mode, as described in reference to FIG. 7 with respect to GUI 700. As a result of the cancellation, the digitization process can terminate and the first document can remain in an unaltered state.

FIG. 4 illustrates an exemplary GUI 400 depicting a digitized second document 406 and options 414 and 416 for the digitized second document. The GUI 400 includes a first region 402 for displaying digitized pages of the second document 406. The GUI 400 also includes a second region 404 for displaying thumbnail images 408 and 412 corresponding to pages in the first document and inserted digitized pages of the second document 406.

In FIG. 4, a page from the second document 406 is depicted as having been digitized using a document scanning device. The second region 404 depicts a placeholder 410 indicating a position in the first document in which the digitized page of the second document 406 will be inserted.

The GUI 400 depicts an option 414 for initiating a re-digitization of the digitized page of the second document 406. In some situations, the digitized page of the second document 406 may appear misaligned or unclear as a result of the digitization process. In such situations, the user can make adjustments to the second document 406 in the document scanning device and can then select the option 414 to re-scan a page from the second document 406.

In some implementations, the GUI 400 includes an option 416 for confirming the insertion of the digitized page of the second document 406. For example, upon digitization of a page, the user can view the digitized page in the first region 402 before the page is inserted into the first document, and can select the option 416 to confirm the insertion. In some other implementations, the digitized page is inserted into the first document automatically without a need for confirmation by the user.

FIG. 5 illustrates an exemplary GUI 500 depicting insertion of a digitized second document 506 into a first document. The GUI 500 includes a first region 502 for displaying digitized pages of the second document 506. The GUI 500 also includes a second region 504 for displaying thumbnail images 508 and 512 corresponding to pages in the first document and a placeholder 510 where the digitized page of the second document 506 will be inserted. In FIG. 5, a page from the second document 506 is depicted as having been digitized and as being inserted into the first document. The second region 504 depicts a placeholder 510 indicating a position in the first document in which the digitized page of the second document 506 will be inserted.

FIG. 6 illustrates an exemplary GUI 600 depicting an option 614 for digitizing and inserting another page into the first document. The GUI 600 includes a first region 602 for previewing digitized pages. The GUI 600 also includes a second region 604 for displaying thumbnail images 606, 608, and 612 that correspond to pages in the first document. The second region 604 also depicts a placeholder 610 indicating a position in the first document in which a digitized page will be inserted. The GUI 600 also depicts an option 614 for initiating digitization of a page.

The GUI 600 can be presented upon insertion of a digitized second document, as described in reference to FIG. 5. The GUI 600 is shown as being in a scan mode. A user can use the GUI 600 to continue inserting non-digitized pages from a second document, e.g., by selecting the option 614 for initiating digitization of a page. A user can exit the scan mode by selecting an option 618. Once the option 318 is selected, the GUI 600 switches to a normal mode as described in reference to FIG. 7 with respect to GUI 700.

FIG. 7 illustrates an exemplary GUI 700 depicting pages 706 and 708 of a first document. The GUI 700 includes a first region 702 for displaying pages of the first document. The GUI 700 also includes a second region 704 for displaying thumbnail images 710, 712, and 714 that correspond to pages in the first document. A user can select a thumbnail image from the second region 704 to display a corresponding page in the first document. In particular, the first document is shown in the first region 702 as having inserted a page 708 that was digitized from a second document using a document scanning device, as described in reference to FIG. 5. A thumbnail image 712 that corresponds to the inserted page 708 is shown in the second region 604, indicating that the page 708 was inserted in the first document.

Exemplary GUI for Automated Contextual Form Generation

FIG. 8 illustrates an exemplary GUI 800 depicting a document 802 with non-digitized form fields. The document 802 includes several non-digitized form fields. For example, a non-digitized form field 804 is shown with the label “Requested Unit,” along with a corresponding non-digitized line where information can be handwritten when the document is in a hard copy format.

In FIG. 8, a mouse cursor 806 is depicted as having been positioned near the non-digitized form field 804. In some implementations, a user can select a position near a non-digitized form field in the document, e.g., by performing a mouse click and, in response to the user selection, a non-digitized field located in proximity to the selected position can be identified. If a non-digitized field is identified as being located in proximity to the selected position, the non-digitized field is digitized. In some implementations, digitization of the non-digitized form field 804 results in creation of an electronically editable form field, e.g., a corresponding text box that is located in proximity to the non-digitized form field 804. The text box can be used to digitally enter information in the form field 804 using a computing device. In some implementations, non-digitized form fields are digitized on-the-fly by continuously analyzing a mouse cursor position and determining whether a non-digitized field is located in proximity to the mouse cursor position.

FIG. 9 illustrates an exemplary GUI 900 depicting a document 902 with an electronically editable form field 904. As described in reference to FIG. 8, the electronically editable form field 904 has been digitized into an electronically editable form field in response to a user selection. A user can enter information into the electronically editable form field 904 by, for example, typing content into the electronically editable form field 904.

FIG. 10 illustrates an exemplary GUI 1000 depicting a document 1002 with an electronically editable form field 1004. The electronically editable form field 904 is shown with content 1006 that has been entered into the electronically editable form field. The user can continue digitizing other non-digitized form fields in the document 1002. The document can be saved, e.g., as a file on a computing device, with the information that the user enters into the electronically editable form fields. The document, along with the information that the user enters into the electronically editable form fields, can also be printed into a hard copy format.

Exemplary Techniques for Automated Contextual Form Generation

FIGS. 11-14 illustrate example techniques for identifying a check box. Each technique can be used independently or in combination with one or more other techniques.

FIG. 11 illustrates an example technique for identifying a check box 1104. FIG. 11 depicts a portion of a document that has been converted into a binarized image format. In FIG. 11, a check box 1104 is identified by identifying edges 1106, 1108, 1110, and 1112 corresponding to the check box 1104. In some implementations, the edges 1106, 1108, 1110, and 1112 corresponding to the check box field 1104 are determined by scanning pixels in the binarized image file, beginning from a position 1102 selected by a user, and determining a white pixel count in an upward, downward, leftward, and rightward direction from the position 1102.

A white pixel count for a particular direction can be determined by counting each white pixel in the particular direction, beginning from the position 1102, until a black pixel is reached. For example, in FIG. 11, for the upward direction, a black pixel is reached when the edge 1110 is reached. The white pixel counts for each direction can be used to measure the pixel distances of edges 1106, 1108, 1110, and 1112 from the position 1102. For example, in FIG. 11, the white pixel count for the upward direction is 2, the white pixel count for the rightward direction is 3, the white pixel count for the downward direction is 5, and the white pixel count for the leftward direction is 4.

FIG. 12 illustrates an example technique for identifying a check box 1204 and 1212. FIG. 12 depicts a portion of a document that has been converted into a binarized image format. In FIG. 12, a check box 1204 is identified by determining whether the size of a region defined by a position 1202 that was selected by a user is within a threshold range. In some implementations, the size of a region is determined based on a horizontal extent for the position and a vertical extent for the position.

A vertical extent 1206 for the position 1202 can be determined by determining white pixel counts, beginning from the position 1202, in the upward direction and in the downward direction plus the pixel that includes the position 1202. Similarly, a horizontal extent 1208 for the position 1202 can be determined by determining white pixel counts, beginning from the position 1202, in the leftward direction and in the rightward direction plus the pixel that includes the position 1202. For example, in FIG. 12, the horizontal extent is eight pixels, which is the sum of the rightward white pixel count of three pixels and the leftward white pixel count of four pixels plus one pixel that includes the position. The vertical extent is also eight pixels, which is the sum of the upward white pixel count of two pixels and the downward white pixel count of five pixels plus one pixel that includes the position.

A check box 1202 can be identified if the horizontal extent 1206 and the vertical extent 1208 each satisfy a threshold range. In some implementations, horizontal and vertical extents satisfy a threshold range when each count is greater than or equal to four pixels and less than or equal to twenty pixels.

In some implementations, a check box is identified by determining whether an aspect ratio for the check box satisfies a threshold. The aspect ratio can be determined using the horizontal extent and the vertical extent. In some implementations, an aspect ratio satisfies a threshold if the aspect ratio is less than or equal to 2.

FIG. 13 illustrates an example technique for identifying a check box 1304 and 1310. FIG. 13 depicts a portion of a document that has been converted into a binarized image format. In some implementations, a check box is identified by determining whether a count of black pixels within a region satisfies a threshold. In some implementations, the threshold is satisfied if the number of black pixels is less than five, e.g., 0, 1, 2, 3, or 4. In some implementations, a region is defined based on pixels included in an area having a height equal to the vertical extent originating from a particular position and by having a width equal to the horizontal extent originating from the particular position.

For example, a check box 1304 has edges 1308, 1310, 1312, and 1314 as determined from a position 1302. The position 1302, which can be based on a user selection, in the check box 1304 is used to determine the vertical and horizontal extents for the check box 1304. In FIG. 13, the check box 1304 has a vertical extent of eight pixels and a horizontal extent of eight pixels. The region 1306 for check box 1304 includes all of the pixels within the area defined by the vertical and horizontal extents. A count of black pixels that fall within the region 1306 can be determined. In FIG. 13, the check box 1304 is depicted as having no black pixels within the region 1306.

FIG. 13 also depicts a text character 1318. The text character 1318 has edges 1322, 1324, 1326, and 1328 as determined from a position 1316. The position 1316, which can be based on a user selection, in the text character 1318 is used to determine the vertical and horizontal extents for the text character 1318. In FIG. 13, the text character 1318 has a vertical extent of eleven pixels and a horizontal extent of nine pixels. The region 1316 for check box 1318 includes all of the pixels within the area defined by the vertical and horizontal extents. A count of black pixels that fall within the region 1316 can be determined. As depicted, the text character 1318 has seven black pixels within the region 1316. Since the number of black pixels exceeds a threshold count, the text character 1318 can be classified as not being a check box.

FIG. 14 illustrates an example technique for identifying a check box. FIG. 14 depicts a portion of a document that has been converted into a binarized image format. In some implementations, a check box is identified by determining whether a count of white pixels located along edges of a check box satisfies a threshold. In some implementations, the threshold is satisfied if the number of white pixels is less than five, e.g., 0, 1, 2, 3, or 4.

FIG. 14 depicts a check box 1404 that has edges 1406, 1408, 1410, and 1412, as determined from a position 1402. The position 1402, which can be based on a user selection, in the check box 1404 is used to determine the edges 1406, 1408, 1410, and 1412. In FIG. 14, the edges 1406, 1408, 1410, and 1412 of check box 1404 do not contain any white pixels. Thus, the total white pixel count for the check box 1404 is zero.

FIG. 14 also depicts an area 1416 that has edges 1418, 1420, 1422, and 1424, as determined from a position 1414. The position 1414, which can be based on a user selection, in the area 1416 is used to determine the edges 1418, 1420, 1422, and 1424. In FIG. 14, there are three white pixels located along the edge 1418, five white pixels located along the edge 1420, two white pixels located along the edge 1422, and four white pixels located along the edge 1424. White pixels shared between edges can be counted once. Thus, the total white pixel count for the area 1416 is eleven pixels. Based on the white pixel count exceeding the threshold, the area 1416 can be classified as not being a check box.

FIGS. 15-17 illustrate example techniques for identifying a line. Each technique can be used independently or in combination with one or more other techniques.

FIG. 15 illustrates an example technique for identifying a line 1504. FIG. 15 depicts a portion of a document that has been converted into a binarized image format. In FIG. 15, a line is detected by scanning downward from a position 1502, where the position 1502 can be based on a user selection, until a slice of black pixels, e.g., a row of black pixels, of a specified length is found. The slice of black pixels can be a contiguous row of black pixels.

The scanning from the position 1502 can be accomplished by scanning each row of pixels, beginning with the row of pixels 1506, which includes the position 1502, until a slice of black pixels of the specified length is found. The rows of pixels can each be of the same specified length as the slice of black pixels. In some implementations, the specified length of a row is between 10 and 20 pixels, e.g., 12, 14, 16, or 18 pixels. The specified length can be divided into two, where each side of the position 1502 can include the same number of pixels. For example, the position 1502 can include eight pixels on the left side and eight pixels on the right side.

In FIG. 15, each row is scanned, beginning from the row 1506, until the slice of black pixels 1504 is reached. The slice of black pixels 1504 can be classified as a line since the slice of black pixels 1504 includes a count of black pixels of the specified length.

FIG. 16 illustrates an example technique for identifying a line 1504. FIG. 16 depicts a portion of a document that has been converted into a binarized image format. FIG. 16 illustrates a technique of identifying a line that may not include a contiguous row of black pixels. In some implementations, a slice of black pixels is tested to identify a count of white pixels that are located in the slice of black pixels. A slice of black pixels can be declassified as a line if the count of white pixels in the slice of black pixels satisfies a threshold.

For example, in FIG. 16, scanning is performed in a downward direction beginning from a position 1602 until a slice of black pixels 1604 is reached. The slice of black pixels 1604 is tested to determine a count of white pixels that are located within the slice of black pixels. In FIG. 16, the slice of black pixels 1604 does not include any white pixels and therefore may be classified as a line.

In another example, in FIG. 16, scanning is performed in a downward direction beginning from a position 1606 until a slice of black pixels 1608 is reached. The slice of black pixels 1608 is tested to determine a count of white pixels that are located within the slice of black pixels. In FIG. 16, the slice of black pixels 1608 is depicted as a dotted line in which the count of white pixels is within a threshold, and therefore the slice 1608 may be classified as a line.

In yet another example, in FIG. 16, scanning is performed in a downward direction beginning from a position 1610 until a slice of black pixels 1612 is reached. The slice of black pixels 1612 is tested to determine a count of white pixels that are located within the slice of black pixels. In FIG. 16, the slice of black pixels 1612 is depicted as text in which the count of white pixels exceeds a threshold, and therefore the slice 1612 is not classified as a line.

FIG. 17 illustrates an example technique for identifying a line 1504. FIG. 17 depicts a portion of a document that has been converted into a binarized image format.

In some implementations, once a line is identified, further scanning can be performed to determine the consistency of subsequent slices of black pixels, i.e., the thickness of the line. If the subsequent slices of black pixels are inconsistent with respect to the count of black pixels in each slice, then the slices can be declassified as a line. In FIG. 17, scanning is performed beginning from position 1702 until a slice of black pixels 1704 is reached. Further scanning of subsequent rows 1705 can be performed to determine whether the slice of black pixels 1704 is or is not a line. In FIG. 17, the subsequent rows 1705 contain inconsistent counts of black pixels and, therefore, the slice of black pixels 1704 can be declassified as a line.

In some implementations, subsequent slices of black pixels that contain a consistent count of black pixels are declassified as a line when the count of subsequent slices of black pixels exceeds a threshold. In some implementations, the threshold is a value less than or equal to 5, e.g., 1, 2, 3, 4, or 5. For example, in FIG. 17, scanning is performed beginning from a position 1706. The scanning reaches several slices of black pixels 1708. The slices of black pixels 1708 are depicted as exceeding a threshold 1710 and, thus, can be declassified as a line.

In cases where a slice of black pixels is found and where a count of subsequent slices of black pixels is within a threshold, then reaching a slice composed entirely of white pixels after the slices of black pixels can further indicate that the slice of black pixels is a line. For example, in FIG. 17, scanning is performed beginning from a position 1712 and slices of black pixels 1714 are reached. The slices of black pixels 1714 are followed by a slice composed entirely of white pixels. Thus, the slice of black pixels 1714 can be classified as a line. In another example, in FIG. 17, scanning is performed beginning from a position 1716 until a slice of black pixels 1718 is reached. Since the slice of black pixels 1718 is followed by a slice composed entirely of white pixels, the slice of black pixels 1718 can be classified as a line.

FIGS. 18-20 illustrate example techniques for determining parameters for a region. Each technique can be used independently or in combination with one or more other techniques.

FIG. 18 illustrates an example technique for determining a height for a region. In some implementations, a height for a region is determined by scanning columns of pixels and identifying the column of pixels having a minimum height. The scanning can originate from a position selected by a user and can continue in a leftward and rightward direction until certain criteria has been satisfied. Each pixel in a column of pixels can be scanned beginning from a baseline, e.g., a line that was identified using techniques described in reference to FIGS. 15-17, and continuing to scan each pixel in the column of pixels in an upward direction until the first black pixel is reached. The height of a column of pixels can be defined by a count of white pixels that were traversed until the first black pixel was reached.

In FIG. 18, columns of pixels are scanned in a leftward and rightward direction originating from the position 1802. In particular, each pixel in each column of pixel is scanned beginning from a baseline and continuing in an upward direction until the first black pixel is reached. In FIG. 18, the minimum height 1806 for the region 1803 is established based on the columns of pixels.

In some implementations, the scanning of columns of pixels is halted if a height of a column of pixels is less than a threshold height. In some implementations, the threshold height is less than ten pixels, e.g., 5, 6, 7, 8, or 9 pixels. In some implementations, the scanning of columns of pixels is halted if a column of pixels is composed entirely of black pixels, e.g., a vertical line 1804.

FIG. 19 illustrates an example technique for determining a width for a region. In some implementations, a width for a region is established by determining the left and right ends of the line. The ends of a line can be determined by scanning a baseline, e.g., a line that was identified using techniques described in reference to FIGS. 15-17, in a leftward and rightward direction until a threshold number of blanks, e.g., white pixels, are found. The baseline can be scanned, pixel by pixel, as a single line or as columns of pixels that together make up a line. In some implementations, the threshold number of blanks for determining an end of a line is a number greater than 3, e.g., 4, 5, 6, 7, 8, 9, or 10.

A count of black pixels that were included in the baseline can be maintained during the scanning and can be used to determine the width of the baseline. The width of a baseline can be defined by a count of black pixels that were traversed until the threshold number of blanks was reached.

In FIG. 19, a baseline 1904 is scanned in a leftward and rightward direction originating from the position 1902. In particular, each pixel in the baseline is scanned in a leftward direction beginning from the position 1902 and continuing until the threshold number of blanks 1906 is found for the leftward direction. The end 1904 of the baseline 1904 can be determined upon reaching the threshold number of blanks 1906.

A baseline need not contain a contiguous row of black pixels. In some implementations, gaps in between columns of pixels that make up a baseline can be measured to determine whether the baseline is a dotted line. Gaps that fall within a threshold range can be ignored in determining the width of a baseline that does not contain a contiguous row of black pixels, e.g., a dotted line. In some implementations, a threshold range for a gap is between 1 and 6 pixels, e.g., 2, 3, 4, or 5.

In FIG. 19, a dotted baseline 1910 is scanned in a leftward and rightward direction, beginning from a location identified using the position 1908, e.g., a position halfway in between columns of pixels 1920 and 1922, to determine a width for the baseline 1910. In some implementations, a width for a dotted region is established by determining the left and right ends of the dotted line. The ends of a line can be determined by scanning a baseline, e.g., a line that was identified using techniques described in reference to FIGS. 15-17, in a leftward and rightward direction until a threshold number of blanks, e.g., white pixels, are found while ignoring gaps in between the columns of pixels 1912, 1914, 1916, 1918, 1920, 1922, 1924, 1926, 1928, and 1930 that make up the baseline. In FIG. 19, the gaps formed by the columns of pixels 1914, 1914, 1916, 1918, 1920, 1922, 1926, and 1928 are within a threshold range. The gap formed by the columns of pixels 1928 and 1930, however, is depicted as not being within the threshold range and, thus, the column of pixels 1928 is identified as the end of the baseline 1910 for the leftward direction.

FIG. 20 illustrates an example region 2003 defined for a detected form field 2000 using one or more techniques. In FIG. 20, the region 2003 for the form field 2000 is defined in response to a user selection 2002 by determining a height 2004 for the region 2003 and a width 2006 for the region 2003. The height and width for a region can be determined using techniques for determining a height and width for a region. The region 2003 can be defined as a potential region where information, e.g., text, may be entered.

FIGS. 21 and 22 illustrate classification of a region as a large or non-large region. The classification of a region as a large or non-large region can be used to determine the bounds for the region.

FIG. 21 illustrates classification of a region. In some implementations, the bounds of a region are determined by classifying a region, as defined in response to a user selection described in reference to FIG. 20, as a large region or a non-large region. In some implementations, a region is classified as a large region or a non-large region by comparing the height of the potential region for the region to a threshold height for the region, e.g., a default feature size for a page. If the height of the potential region is greater than 2, e.g., 2.1, 2.2, 2.3, 2.4, 2.5, or 2.6 times the height of the threshold height, the region can be classified as a large region. Otherwise, the region can be classified as a non-large region.

In FIG. 21, the region 2100 is depicted with its potential region height 2104 and a threshold height 2102. Both the potential region 2104 and the threshold region 2102 share the same lower edge. In particular, the potential region 2104 is clamped to a maximum height for the region 2100. In some implementations, the height used to clamp the potential region 2104 is based on the type of font and font size that will be used to populate the form field. A comparison can be made between the potential region height 2104 and the threshold height 2102 to classify the region 2100 as a large region or a non-large region.

FIG. 22 illustrates classification of a region by comparing a ratio of the height of the potential region to a threshold height. In some implementations, if the ratio is greater than 2, e.g., 2.1, 2.2, 2.3, 2.4, 2.5, or 2.6 times the height of the threshold height, then the region can be classified as a large region. In FIG. 22, a region 2200, as defined in response to a user selected position 2202, is classified by comparing the height of the potential region 2206 for the region 2200 to a threshold height 2204 for the region 2200. Both the potential region 2206 and the threshold region 2204 share the same lower edge. Since the height of the potential region 2206 is depicted as being greater than twice the height of the threshold height 2204, the region 220 can be classified as a large region.

FIG. 22 also depicts a region 2207, as defined in response to a user selected position 2208, is classified by comparing the height of the potential region 2210 for the region 2207 to a threshold height 2204 for the region 2207. Both the potential region 2210 and the threshold region 2204 share the same lower edge. Since the height of the potential region 2206 is depicted as being less than twice the height of the threshold height 2212, the region 2207 can be classified as a non-large region.

FIG. 23 illustrates a bounding technique for non-large regions. In some implementations, a user selected position that was used to identify a non-large region is checked to determine whether the non-large region should be digitized. A region can be digitized if a user selected position that was used to identify the region is within a threshold distance from the top of the region. Otherwise, the region may not be digitized. In some implementations, the threshold distance is a less than 12 pixels, e.g., 8, 9, 10, or 11.

FIG. 23 depicts a region 2300 that can be identified in response to example a user selected positions 2302 and 2306. Although only one user selected position is needed to identify a region, both user selected positions 2302 and 2306 are shown for purposes of illustrating threshold distance. In FIG. 23, if the region 2300 was defined in response to the user selected position 2302, the distance 2304 for the user selected position 2302 can be measured from the top of the region 2300. If the distance 2304 is within a threshold distance, then the region 2300 can be digitized. In another example, if the region 2300 was defined in response to the user selected position 2306, the distance 2308 for the user selected position 2306 can be measured from the top of the region 2300. In FIG. 23, the user selected position 2306 is shown outside of a threshold distance 2310, and thus, the region may not be digitized.

FIG. 24 illustrates a bounding technique for large regions. In some implementations, a user selected position that was used to identify a large region is checked to determine digitization parameters for the large region. A user selected position that is near the top of the large region can be digitized as a top-aligned electronically editable form field, e.g., a text field. A top-aligned electronically editable form field can allow the user to enter information using one or more lines and can allowed the user to input newlines. A user selected position that is near the bottom of the large region can be digitized as a bottom-aligned electronically editable form field that includes one or more lines.

FIG. 24 depicts a region 2400 depicted with user selected positions 2402, 2406, and 2410. The user selected position 2402 is depicted as being near the top of the large region 2400. Based on the user selected position 2402, the region 2400 can be digitized as a top-aligned electronically editable form field. The user selected position 2410 is depicted as being near the bottom of the large region 2400. Based on the user selected position 2410, the region 2400 can be digitized as a bottom-aligned electronically editable form field. In some implementations, a region is not digitized when a user selection position is located in the middle of the region. The top, middle, and bottom of a region can be defined in proportion to the region's height. For example, the top and bottom of the region 2412 can be defined based on a threshold pixel percentage, e.g., the top 2404 and bottom 2412 of the region 2412 can be, e.g., the top and bottom 30 percent of pixels, respectively, in the column of pixels defining the region's height while the middle 35 percent of pixels in the column of pixels can be the middle 2408 of the region 2412. In some implementations, a user selected position in the middle 2408 of the region 2412, e.g., the user selected position 2406, results in cancellation of the form field detection process. Instead, a default electronically editable form field can be placed at the user selected position.

FIG. 25 illustrates an example technique for determining edge types for a region 2502. In some implementations, an edge type for an edge is determined for purposes of bounding a region that is defined by the edge. An edge can be classified as an empty space, a solid line, or as text. In some implementations, the edge type for an edge is determined by scanning pixels in the column of pixels that define the edge. The scanning can be performed beginning from a baseline and proceeding in an upward direction until the height of the column of pixels is reached. An edge defined by a column of pixels composed entirely of white pixels can be classified as an empty space. An edge defined by a column of pixels composed entirely of black pixels can be classified as a solid line. An edge defined by a column of pixels composed of a threshold percentage, e.g., less than twenty percent, of black pixels can be classified as text.

In FIG. 25, the region 2502 is defined by a right edge 2504 and a left edge 2506. The edge type for the right edge 2504 can be determined by scanning the column of pixels 2505 that defines the right edge 2504, beginning from the baseline 2501 and continuing in an upward direction until the height of the column of pixels 2505 is reached. In FIG. 25, the column of pixels 2505 is depicted as being composed of all black pixels and, thus, the column of pixels 2505 can be classified as a solid line.

Similarly, the edge type for the left edge 2506 can be determined by scanning the column of pixels 2507 that defines the left edge 2506, beginning from the baseline 2501 and continuing in an upward direction until the height of the column of pixels 2507 is reached. In FIG. 25, the column of pixels 2507 is depicted as being composed of some black pixels and, thus, the column of pixels 2507 can be classified as text.

In some implementations, a region that is classified as a large region, and is assigned a top-aligned electronically editable form field, requires that the left edge and the right edge for the region be solid lines.

FIG. 26 illustrates bounding a width of a region. In some implementations, a region width is required to be greater than a minimum threshold size. In some implementations, the minimum threshold size is a value between 20 and 30 pixels, e.g., 22, 24, 26, or 28 pixels. The minimum threshold size can vary depending on the edge types of the right edge and left edge that define the region. In some implementations, when the right and left edges for a region are both text, the minimum threshold size is a value between 40 and 50 pixels, e.g., 42, 44, 46, or 48 pixels.

In some implementations, a region width that is larger than a maximum threshold size for a document is adjusted to a default width. For example, if the region width is larger than a threshold width, e.g., ½, the width of the page, then the region width can be adjusted to a default width, e.g., ⅓ the width of the page. The height of the region, e.g., unbounded region 2604, can also be adjusted based on the type of font and font size being used to populate the form field.

In FIG. 26, an unbounded region 2604 was identified in response to a user selected position 2602. The unbounded region 2604 is determined to exceed a maximum threshold size and, thus, is bounded using a default width. In response to the determination, the unbounded region 2604 is adjusted to a bounded region 2608 and is placed at a position corresponding to the user selected position 2602.

FIG. 27 illustrates positioning of an electronically editable form field relative to a user selected position. In some implementations, the position of an electronically editable form field can be adjusted relative to a user selected position. For example, an electronically editable form field 2704 can be left aligned relative to the user selected position 2702. In another example, an electronically editable form field 2708 can be centered relative to a user selected position 2706. In another example, an electronically editable form field 2710 can be right aligned relative to a user selected position 2712.

FIG. 28 illustrates positioning of an electronically editable form field in a region. In some implementations, an electronically editable form field is positioned at the user selected position. For example, as depicted in FIG. 28, an electronically editable form field 2804 is positioned at the user selected position 2802.

In some implementations, electronically editable form fields for a region can be snapped in a position relative to a user selected position. For example, an electronically editable form field can be snapped to a left edge for a region when a user selected position is within a threshold range from the left edge. In some implementations, the threshold value is less than 25 pixels, e.g., 5, 10, 15, or 20 pixels. For example, as depicted in FIG. 28, an electronically editable form field 2808 is snapped to a left edge 2807 since the user selected position 2806 is within a threshold range 2814. Similarly, an electronically editable form field can be snapped to a right edge for a region when a user selected position is within a threshold range from the right edge. For example, as depicted in FIG. 28, an electronically editable form field 2812 is snapped to a right edge 2811 since the user selected position 2810 is within a threshold range 2814.

Exemplary Document Assembly Process

FIG. 29 illustrates an exemplary process 2900 for inserting pages from a second document into a first document. In some implementations, process 2900 can be implemented using the architecture described in reference to FIG. 33.

In some implementations, process 2900 can begin by displaying one or more pages of a first document in a first region on a user interface (2902). The first document can be obtained, for example, from other computing devices, external devices (e.g., cameras, portable hard drives, flash drives, network-attached storage devices), or cloud-based storage systems. Thumbnail images of the one or more pages of the first document can be displayed in a second region on the user interface.

Process 2900 can continue by receiving a user selection for inserting one or more pages from a non-digitized second document into the first document (2904). For example, a user can select an option for inserting pages from the non-digitized second document, e.g., a document that is available as a hard copy, into the first document.

Process 2900 can continue, in response to the user selection, by digitizing the one or more pages of the non-digitized second document using a document scanning device (2906). For example, the non-digitized second document can be digitized using a document scanning device, e.g., a scanning apparatus, that scans the second document into a digital format, e.g., in an image or a portable document format.

Process 2900 can continue by inserting the one or more pages of the digitized second document into the first document (2908). Once inserted, the inserted pages are displayed as part of the first document on the user interface.

Exemplary Automated Contextual Generation Process

FIG. 30 illustrates an exemplary process 3000 for digitizing form fields in response to a user selection. In some implementations, process 3000 can be implemented using the architecture described in reference to FIG. 33.

In some implementations, process 3000 can begin by displaying a first document on a user interface, the first document containing one or more non-digitized fields (3002). The non-digitized fields in the first document can be non-digitized form fields or check boxes.

Process 3000 can continue by receiving a user selection of a position in the first document (3004). For example, the user selection can be a mouse click made on a position in the first document.

Process 3000 can continue by identifying, in response to the user selection, a non-digitized field located in proximity to the selected position (3006). The non-digitized field can be, e.g., a check box or a form field. Identification of non-digitized fields is described in reference to FIG. 31.

Process 3000 can continue by digitizing the identified non-digitized field (3008). Depending on the non-digitized field, the digitization can result in converting a non-digitized check box into an electronically editable check box or a non-digitized form field into an electronically editable form field. Electronically editable check boxes can be electronically ticked in response to, e.g., a user selection of the electronically editable check boxes. Users can enter information directly into electronically editable form fields using, e.g., a keyboard device.

Exemplary Digitization Process

FIG. 31 illustrates an exemplary process 3100 for digitizing fields. In some implementations, process 3000 can be implemented using the architecture described in reference to FIG. 33.

In some implementations, process 3100 can begin by creating a black-and-white image of a document page (3102). A document page can be converted into an image format, e.g., a bitmap file, and can be rendered in a black-and-white color. One example method of rendering a document page into black-and-white involves binarizing the image. The binarization of an image file can result in individual pixels in the image file being marked as “white” pixels if their value is greater than some threshold value and as “black” pixels otherwise. Using the binarized pixels, the image file can be scanned to determine whether a non-digitized field is a check box or a form field.

Process 3100 can continue by receiving a user selection of a position in the document page (3104). For example, the user selection can be a mouse click made on a position in the first document.

Process 3100 can continue by determining whether a region identified by the position is a check box (3106). A determination of whether a region is a check box can be made using techniques described in reference to FIGS. 11-14.

If the region was determined to be a check box, the process 3100 can continue by digitizing the check box (3108). For example, the check box can be digitized by placement of an electronically editable check box at a location defined by the user selected position. The electronically editable check box can be sized according to the non-digitized check box using measurements that were made during the check box detection process, as described in 3106.

If a check box was not found, the process 3100 can continue by determining whether the region is a form field (3110). A form field can be identified by determining whether the region identified by the position includes a line. Line detection can be performed using techniques described in reference to FIGS. 15-17. Once a line is detected, parameters for a region defined by the line can be determined. The parameters can include the height and width of the region and can be determined, e.g., using techniques described in reference to FIGS. 18-20.

Using the parameters of the region, the region can be classified as a large or non-large region using techniques described in reference to FIGS. 21-22. Classification of the region as a large region or a non-large region can affect how the form field in the region is digitized. In some implementations, a user selected position that was used to identify a non-large region can be checked to determine whether the non-large region should be digitized, as described in reference to FIG. 23.

In some implementations, a user selected position that was used to identify a large region can be checked to determine digitization parameters for the large region, as described in reference to FIG. 24. For example, a user selected position that is near the top of the large region can be digitized as a top-aligned electronically editable form field, e.g., a text field. A top-aligned electronically editable form field can allow the user to enter information using one or more lines and can allowed the user to input newlines. A user selected position that is near the bottom of the large region can be digitized as a bottom-aligned electronically editable form field that includes one or more lines.

In some implementations, the edge types for the region are determined. Edge types can be determined using techniques described in reference to FIG. 25. In some implementations, a region that is classified as a large region, and is assigned a top-aligned electronically editable form field, requires that the left edge and the right edge for the region be solid lines. If the left and/or right edges are not solid lines, then the region may not be assigned a top-aligned electronically editable form field and may instead use a bottom-aligned electronically editable form field.

Additional measurements of the region can be made to ensure certain sizing criteria is satisfied. For example, the region's width can be resized to fall within a threshold range. In some implementations, a region width is required to be greater than a minimum threshold size. In some implementations, a region width that is larger than a maximum threshold size for a document is adjusted to a default width. Resizing, or bounding, of a region width is described in more detail in reference to FIG. 26.

If the region was determined to be a form field, the process 3100 can continue by digitizing the form field (3112). The form field identified in the region can be digitized by placing an electronically editable form field, e.g., a text box, at a location defined by the user selected position, as described in reference to FIG. 27. In some implementations, an electronically editable form field is positioned at the user selected position, as described in reference to FIG. 28. The electronically editable form field can be sized according to the form field using measurements that were made during the form field detection process as described in 3110. An electronically editable form field for a region can also be snapped in a position relative to a user selected position, as described in reference to FIG. 28.

Otherwise, if a form field was not found, the process 3100 can, optionally, continue by creating a default electronically editable form field at the position (3114). For example, if no form field was found, a default-sized electronically editable form field can be positioned at the user selected position.

Exemplary Operating Environment

FIG. 32 is a block diagram of an exemplary operating environment for a device capable of running a document assembly and automated contextual form generation application. In some implementations, devices 3202 a and 3202 b can communicate over one or more wired or wireless networks 3210. For example, wireless network 3212 (e.g., a cellular network) can communicate with a wide area network (WAN) 3214 (e.g., the Internet) by use of gateway 3216. Likewise, access device 3218 (e.g., IEEE 802.11g wireless access device) can provide communication access to WAN 1114.
